The Haunted Bus — Marjorie Weinman Sharmat

Weird things are happening on Harry's bus.

Windows are opening and closing without anyone's help.

The bus is making strange screaming sounds.

And there's a scary pile of bones under Diane's seat.

Is the school bus haunted?

Charlie and Max have to know.

How can they find out?

They will have to go into the old garage at night! What will they do if ghosts are there?

One thing is sure. Before the night is over, Charlie and Max will be frightened out of their wits -- and so will the "ghosts." Just wait and see.
